Mrs Devers, 64, was last year found guilty of eight charges under the Weights and Measurements Act.
She had refused to replace imperial weighing scales on her fruit and vegetable stall at Ridley Road Market in Dalston, east London.
The market trader, from Wanstead, east London, was given a two-year conditional discharge and ordered to pay £5,000 costs following the case, which was brought by Hackney Council.
I could almost see it if this was a big chain. But they are going after a stall in a farmer’s market for selling things by the pound. Is that really such a big crime?
